<p>
    Since version 2.10, GTK+ provides the GtkAssistant widget as a replacement
    for the <span class="structname">GnomeDruid</span> widget in the libgnomeui 
    library.
  </p>
<p>
    Conceptually, both <span class="structname">GtkAssistant</span> and
    <span class="structname">GnomeDruid</span> do the same task, but there are 
    several areas where the API has been completely redesigned, so this 
    chapter covers the main changes between both widgets.
  </p>
<div class="section" lang="en">

<a name="inserting-pages"></a>Inserting pages</h2></div></div></div>
<p>
      <span class="structname">GnomeDruid</span> was implemented as a container for
	 <span class="structname">GnomeDruidPage</span> abstract objects, which are
         implemented by the <span class="structname">GnomeDruidPageEdge</span> and 
         <span class="structname">GnomeDruidPageStandard</span> widgets. Instead, 
         <span class="structname">GtkAssistant</span> allows any widget to be a page, 
         and implements per-page settings (such as page type or title) as 
         child properties. So instead of:
    </p>
<pre class="programlisting">
/* Page 1 */
page = gnome_druid_page_edge_new (GNOME_EDGE_START);
gnome_druid_page_edge_set_test (GNOME_DRUID_PAGE_EDGE (page),
                                "Welcome to the assistant, it will make your life easier");
gtk_widget_show (page);
gnome_druid_append_page (GNOME_DRUID (druid), GNOME_DRUID_PAGE (page));

/* Page 2 */
page = gnome_druid_page_standard_new ();
gtk_container_add (GTK_CONTAINER (GNOME_DRUID_PAGE_STANDARD (page)-&gt;vbox,
                   create_page1 ());
gtk_widget_show_all (page);
gnome_druid_append_page (GNOME_DRUID (druid), GNOME_DRUID_PAGE (page));

/* Page 3 */
page = gnome_druid_page_edge_new (GNOME_EDGE_FINISH);
gnome_druid_page_edge_set_test (GNOME_DRUID_PAGE_EDGE (page),
                                "Now you are done, your life is easier");
gtk_widget_show (page);
